Programme overview
Introduction:
Wide area monitoring gives grid operators a time-aligned view of phase angles, frequency and oscillations that SCADA scans every few seconds cannot provide, yet many PMU fleets deliver noisy, gappy data that nobody trusts in the control room. This Core Concept course takes engineers through the synchrophasor measurement chain, from phasor estimation and GPS or PTP timing to phasor data concentrators, data quality and analytics for oscillation, stability and islanding detection. Participants produce a WAMS Deployment and Use-Case Plan with a Post-Event Analysis Report.
Course Objectives:
- Evaluate PMU phasor estimates against IEEE C37.118.1 accuracy metrics such as total vector error, frequency error and ROCOF error under steady-state and dynamic conditions
- Design a WAMS architecture covering PMU placement for observability, time source redundancy, PDC hierarchy and data transfer with IEEE C37.118.2 or IEC 61850 streams
- Diagnose synchrophasor data quality problems including timestamp errors, dropped frames, latency and bad channels, and set data quality flags and cleansing rules
- Configure oscillation detection, mode meter, angle and voltage stability monitoring and islanding detection applications with alarm thresholds for the control room
- Reconstruct a grid disturbance from PMU records to identify the initiating event, sequence and oscillation behaviour for a post-event report
- Prepare a WAMS deployment and use-case plan linking PMU data to state estimation, wide-area protection and control, renewables monitoring and cyber security controls
Target Audience:
- Power system engineers who study grid dynamics, validate models and specify measurement requirements for transmission networks
- Protection engineers who configure relays with integrated PMU functions and analyse disturbance and fault records
- Control-room engineers who supervise real-time displays, respond to oscillation and angle alarms and support dispatchers during events
- Grid planning engineers who decide PMU placement, communications capacity and monitoring needs for new substations and renewable connections
- Energy management system and operational technology specialists who integrate PMU and PDC data with EMS, SCADA and historians

Conclusion:
A wide area monitoring system earns its place when accurate, well-timed PMU data reaches applications that operators and engineers use. The five days move from phasor estimation and accuracy, through timing, PMU placement and PDC architecture, to data quality, oscillation, stability and islanding analytics, then wide-area protection and control, EMS integration, renewable plant monitoring and cyber risk. The final day produces a deployment and use-case plan and a post-event analysis ready for peer challenge.
